why does a laburnum not flower, bought mine 2010 (6ft) it flower 1st year, but then failed to flower since. i potash and manure mulch spring/autumn, no grass around it. not in shade, theres one in the ditch and flowers every year, my soil is peaty

young trees bought from nurseries are usually well cared for and probably imported from warmer climates, It is easier to sell a tree in flower , hence yours was in flower first year, it now has to acclimatise to Irish growing conditions and can take a couple of years to adjust,
But your problem why is it not flowering now,
1 It could have exhausted itself in the first year and needs to build up reserves to flower again.
2 IFlowering buds could have been damaged by frost
3 The roots could be damaged on planting
4 could it be standing it too wet soil.
5 It may have to wait maturity in 3/4 years before flowering
Give it high potash feed but not manure or mulch. make sure its staked and not rocking in soil.
Relax nature will take its course. And it will be well worth it.
Oh remember its seed pods are highly poisonous keep away from children

thks Greenage, soil is not wet, roots ok and stake ok. i will stop manure mulching, any suggestions? just bark or grass clippings as mulch, thought it be use to the weather by now, and since the one in the wild is flowering, it can't be frost. its an aweful pity, thats all i can say.
